Vitaceae Vitaceae Anna Trias Blasi Woody or herbaceous climbers. Hermaphroditic, or polygamo-dioecious. Stems generally conspicuously lenticellate, bark sometimes shredding. Tendrils simple, bifurcate, 2–14 branched (adhesive discs on each tip in Parthenocissus and Tetrastigma obtectum), usually leaf-opposed, rarely absent, sometimes associated with the inflorescence. Leaves petiolate, simple and palmately veined or digitately or pedately compound, lobed or unlobed, usually with ‘pearl glands’ (small multicellular, stalked, caducous spherical structures), margin variously toothed. Inflorescences paniculate, corymbose or thyrsoid, leaf-opposed, pseudo-terminal, or axillary. Flowers small, generally pedicellate, sometimes subsessile, actinomorphic, hypogynous, 4–5-merous. Calyx cupuliform, sometimes with 4–5 small lobes. Petals valvate, 4–5, free or connate and forming a calyptra, apex generally cucullate. Stamens 4–5, antepetalous, anthers medifixed dehiscing longitudinally, tetrasporangiate. Disc intrastaminal, cupular or anular, entire or lobed, mostly adnate to the ovary; sometimes inconspicuous. Ovary superior, 2-locular; style simple, stigma mostly inconspicuous, sometimes capitate or discoid, 4-lobed in Tetrastigma. Fruit a 1–4-seeded berry, seeds endotestal with an abaxial chalazal knot and an adaxial raphe. A family of approximately 14 genera and 900 species distributed pantropically in Asia, Africa, Australia, the Neotropics and the Pacific with some species in temperate areas. Eight genera and 27 species in Nepal, including 2 cultivated species. Key to Genera 1a Petals united; forming a calyptra (hood structure) and dropping off as a unit at anthesis.

Vitis L., Sp. Pl. 1:202 (1753). Woody climbers, polygamo-dioecious. Stem with shredding bark. Tendrils usually 2-furcate, leaf-opposed, sometimes associated with the inflorescence, without adhesive discs. Leaves simple, sometimes lobed. Inflorescence leaf-opposed, paniculate. Flowers bisexual and unisexual, 5-merous. Calyx cupuliform or 5–dentate. Petals 5, united at the apex, separating at the base and shed together as a calyptra. Stamens 5, abortive in female flowers. Disc annular or 5-lobed, fused to the ovary, ovary rudimentary in male flowers. Style conical, short, stigma inconspicuous. Fruit 2–4-seeded, globose. Seeds obovoid to pyriform, adaxial side 2-furrowed, abaxial side 1- furrowed with a rounded, spathulate or elliptic chalazal knot. About 65 species, mainly in the northern hemisphere with some species extending into subtropical SAmerica and Asia. Three species native to Nepal, with one species, the grape, cultivated. Vitis includes V. vinifera, the grape, which is economically important both as a fresh or dried fruit and as the basis of the wine industry. It is cultivated in the Tarai and can be distinguished by its leaves which are oval to suborbicular, shallowly to deeply 3–5-lobed with a deeply cordate base and deeply and irregularly toothed margin. Its fruits are 15–25 mm in diameter. Vitaceae Key to Species 1a Leaves oval to suborbicular, shallowly to deeply 3- or 5-lobed, base deeply cordate, margin deeply and irregularly toothed.
